Two IgE molecules on FcεRI receptors attached to a mast cell can be cross-linked by (A) a single  the cross-linking of IgE-receptor complexes on mast cells, basophils, and rat mers as a DNP-biotin conjugate, served to cross-link anti-. DNP IgE-receptor  Methods: Monocytes purified from healthy donor blood samples were cultured for 4 to 96 hours with media alone, a cross-linking anti-IgE antibody or control IgG. Not only is it is necessary to cross-link very few IgE and FcεRI molecules in this way, compared with IgG and FcγR, but the affinity of IgE for FcεRI (Ka ≈ 1010  As a result of IgE cross-link- ing, mast cells and basophils can release their well- known inflammatory mediators and cytokines, such as histamine and TNF-a.

That's what cross-linking means. Cross-linking of the FceRI-bound IgE leads to cellular activation, resulting in immediate release of preformed granular components such as histamine and tryptase and subsequent production of lipid mediators (prostaglandins and leukotrienes) and cytokines (IL-4 and IL-5). Crosslinking används för att bromsa sjukdomsförloppet vid keratokonus och andra liknande hornhinnesjukdomar. Målet är att din syn inte ska fortsätta att försämras. Conclusions: IgE cross-linking drives monocyte proinflammatory processes and autoregulatory IL-10 in a serum IgE-dependent manner. In contrast, monocyte phagocytic function is critically impaired by IgE cross-linking. Our findings suggest that IgE cross-linking on monocytes may contribute to allergic disease by both enhancing detrimental inflammatory When you have cross-linking of an allergen, it causes a signaling cascade that causes mast cells and basophils to degranulate and release mediators that characterize the allergic response.
